Power Industrial Frequency Line Parameter Measurement Device Calibration System
Calibration Set for Grid Line Impedance Tester
Product Introduction
The Power Frequency Line Parameter Tester Calibration Device is a device used to calibrate and verify the accuracy and precision of power frequency line parameter testing instruments. Power frequency line parameter testers are commonly used to measure and analyze various parameters in power systems, such as voltage, current, power factor, frequency, etc., to assess the performance and quality of the power system.
The main function of the calibration device is to provide reference signals with known and accurate values. By comparing these signals with the measurements obtained from the power frequency line parameter tester, the calibration device checks and adjusts the instrument's measurement results to ensure their accuracy and consistency. The calibration device typically incorporates a highly stable reference source and precise measurement circuits to generate stable and accurate signals, providing reliable calibration results.
Product Features
1.The calibration device can calibrate the zero sequence impedance, zero sequence capacitance, positive sequence impedance, positive sequence capacitance and other measurement functions of the industrial frequency line parameter tester. The impedance value, impedance angle and capacitance are highly accurate, the quantity value is continuously adjustable, and the adjustment fineness is small and the range is large.
2.The device can simulate the field similar positive sequence or zero sequence circuit, wide frequency response range, current input range, capacitance and impedance can be convenient traceability.
3.The calibration device is divided into two main parts: upper computer and lower computer, and the two parts communicate through RS-232 serial port. The upper computer provides users with a friendly control interface in the form of PC human-computer interaction, which is used to select the content, mode and parameters of the calibration; the lower computer is a specific part that responds to various command parameters of the upper computer and implements the calibration work. Stable performance, hardware and software design ideas are novel and targeted.
